I have just finished the long coat and pinned the 2 fronts at the shoulders. The collar is a 2x2 ribbing which needs to be attached as soon as the shoulder seams are done.([I]see picture, I hope it comes out[/I])

My question is on [COLOR=“Blue”]how to sew these shoulder seams up[/COLOR].
Can I use the method described in Studioknits online book for horizontal seams ([I]as I’ve read that the backstitch seam is not as invisible)[/I];.
As you can see the stitches are in both Knit and Purls with the cables going every which way; and the sleeves are made up of 2 rows KNIT, 2 rows PURLS
So does this mean when I sew them up I have to change the stitches as I go along?
I also want to know if I follow this method, I would be seaming the edges on the [COLOR=“Blue”]right side facing of the work[/COLOR], yes?
Any advice on the best method would be most welcomed.
Thank you!:knitting:
P.S As you might have deduced, I am new to this!
